UNITED STATES PATENT OFFICE.

HUB-FASTENER.

Application filed September To all whom 'it may concern:

Be it known that I, ARIVED E. RoxBERG, a citizen of the United States,residing at Brainerd, in the county of Crow Wing, State of Minnesota,have invented certain new and useful Improvements in Hub-Fasteners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to devices employed for securing hubs upon axlejournals, and has for one of its objects to simplify and improve theconstruction and increase the etliciency and utility of devices of thischaracter.

Another object of the invention is to provide a fastening means whereinthe use of threaded spindles and nuts are obviated and the fasteningmeans automatically applied, and removable by the fingers of theoperator, and without the necessity for employing Wrenches or other likeim lements.

With these and other o jects in view, the invention consists in an ax ejournal having a cavity in its outer end provided with a reducedcommunicating aperture, a cap engaging over the outer end of thejournal, and spring actuated catch devices swinging from the cap andoperating through the aperture to lock the cap to the journal andprovided with projections to produce finger grips for the operator.

The invention further consists in certain novel features of constructionas hereafter shown and described and then specifically pointed out inthe claim, and in the drawings illustrative of the preferred embodimentof the invention.

Figure 1 is a longitudinal section of the improved device. Fig. 2 is anend elevation. Fig. 3 is a section on the line 3--3 of Fig. 1.

The improved device may be applied to any of the various forms of axlejournals in use, but is more particularly applicable to the journals ofthe larger class of vehicles, such as farm and freight wagons and thelike, and for the purpose of illustration the improved device is shownapplied to an axle journal of this class in which 10 represents theskein or shell fitting over the outer end of a wooden axle 11 of theordinary construction. The outer end of the skein 10 is provided with acavity or recess 12, and the Specification of Letters Patent.

,l skein is secured to the wooden axle 11 by a lag screw 18. The recess12 is formed with a reduced aperture 14 providing communication throughthe outer end of the skein and whereby overhanging portions l5 areformed, as shown.

Fitting over the outer end of the skein is a cap 16 preferably with awrench surface 17. The cap 16 is provided with a central aperture 18preferably registering with the aperture 14 of the skein and providedwith spaced ears 19-20 and extending outwardly from the cap at the sidesof the aperture 1S.

Swingiiw between the ears 19-2O are two catch mem ers 21-22, the catchmembers adapted to pass through the aperture 14 and into the recess 12of the journal when the cap member is positioned upon the journal, theterminals of the catch members having lateral projections 23-24 engagingin the rear of the overhanging portions 15, as shown. The outer faces ofthe projections 23 24t are oppositely inclined, as shown, so that whenthe cap is located over the journal the catch members will automaticallyenter the aperture 14 and extend in the rear of the overhanging portions15, the catch members being provided with a spring 25 to maintain themyieldably in their extended position.

A portion of the hub is represented at 26, and the inner face of the cap16 is designed to bear against the outer face of the hub, while theinner face of the hub bears against the usual collar 27 of the skein. Attheir outer ends the catch melnbers .2122 are extended laterally asshown at 28-29, and extend beyond the wrench engaging portion 17 of thecap, and form effectual finger grips to enable the operator to easilycompress the catch members and thus release the projections 23-24 fromthe overhanging portion 15. By this means the device may be readilydetached from the hub without the use of a wrench or implement otherthan the fingers of the operator, while at the same time the sprinfr 28efl'ectually retains the cap in locked position relative to the skein.It will be noted that the outer portions of the ears 19--20 are roundedto correspond to the outer portions of the arms 21-22, so that the outerportions of the arms and the outer portions of the ears correspond henceno object with which the ends of the ears and the outer ends of the armsengage will produce any movement of the arms. It will also be noted thatthe wholly within the interior of the hub band,

not shown. By this means no object with which'the 'hub would be liableto come in contact when in use will cause the release of the arms. Thisis an important feature of the invention and adds materially to itsefficiency and utility. By this simple means it will be obvious that thehub is firmly secured in position upon the journal by simply depressingthe cap over the end of the ournal with the catch members passing intothe recess 12 and their barbed inner ends engaging in the rear of theoverhanging portions l5, as described.

When the device is to be detached, the catch members 21-7-22 arereleased'by the pressure of the fingers of the operator upon theprojections 28-29 as above described. To replace the device it is onlynecessary to force it inwardly over the outer end of the sleeve, theinclined faces of the projections engaging with the edges of the openingand thereby being automatically compressed and caused to again engage inthe rear of the overhanging portions.

The improved device is simple in construction, can be inexpensivelywmanufactured, and applicable to axle journals of various sizes, and toaxle journals employed upon vehicles of various constructions.

What is claimed is :d The combination with an axle journal 'having ahollow outer portion and an in- Vwardly directed flange at the outerterminal of the hollow portion, a cap fitting over the hollow terminalof the journal and adapted to bear against the hub which is located uponthe journal, said cap having a central aperture communicating with theinterior of the journal and provided with spaced ears extendinginadvance thereof, a pin extending through said ears, two arms swingingupon said pin and extending through the aperture of the cap and intolthehollow of the journal and having laterally directed terminals en gagingbehind said flange, lugs projecting laterally from said arms and betweensaid ears and between. the pin and the cap and extending beyond theears, whereby means.

are provided for releasing the arms and protecting the lugs.

In testimony whereof, I affix my signature, in presence of twowitnesses.
